Answer: (B)

Top soil

• Humus is the organic component of soil, formed by the decomposition of leaves and other plant material by soil microorganisms.

• The more humus found in topsoil, the richer it is in nutrients and the better conditions it has for growing plants.

So, option B is the correct answer.
